Dispensing valve with elastic sealing tube

Abstract

A dispensing valve comprises a first body portion having a connecting assembly for joining to a fluid outlet. A second body portion comprises a relatively rigid, elongated member having a lateral side wall terminating in a free end. A discharge orifice is formed in the lateral side wall of the second body portion. Mounted on the second body portion in tightly encircling relationship to sealingly overlie the discharge orifice and prevent fluid flow therethrough is a resilient tubular member. An operating handle is joined to the tubular member for selectively and resiliently deflecting the tubular member away from the discharge orifice to permit flow therethrough.

What is claimed is: 
     
       1. A manually operable dispensing valve comprising: a body member including connecting means for connecting the body member to a fluid supply source, said body member including an elongated relatively rigid body portion extending outwardly from the connecting means and terminating in a free end: a laterally opening discharge orifice in the rigid body portion adjacent the free end thereof and a fluid passageway extending through the body member for conducting fluid from the supply source to the discharge orifice;   a resilient tubular member positioned over the rigid body portion in tensioned surrounding relationship thereto to sealingly overlie the discharge orifice;   operating means for deflecting the tubular member away from the orifice to permit fluid flow therethrough, said operating means comprising an operating lever pivotally mounted on the body member and having an end joined to the tubular member at a location exterior of the body adjacent the discharge orifice to selectively deflect the tubular member away from the outlet orifice upon actuation of the lever.     
     
     
       2. A dispensing valve as defined in claim 1 wherein the relatively rigid body portion is cylindrical. 
     
     
       3. A dispensing valve as defined in claim 1 including a relatively rigid housing carried by the body portion and enclosing the resilient tubular member, the housing being open in the area radially aligned with the outlet orifice to permit deflection of the tubular member away from the outlet orifice while the housing is in place thereon. 
     
     
       4. A dispensing valve as defined in claim 3 wherein the housing encloses the resilient tubular member throughout a circumferential extent of greater than 180°.
